Exploring sounds in Badgers

Badgers class transformed into scientists today as we explored different sounds. During our investigations were able to create a variety of sound pitches by filling water bottles with different amounts of water,  see the vibrations made when hitting a drum by putting rice on the top and making pan pipes by cutting straws at different lengths. However, our favourite investigation had to be our telephone cups! By keeping the string very straight and tight, the results were amazing! We couldn’t believe how our voices travelled through the string. We even got very technical and managed to ‘add in calls’ by twisting our string together!
